omap3: clock: Fix the DPLL freqsel computations
Fix the freqsel value computation. Use n instead of (n+1)
The formula in the TRM uses a zero-based N, hence the (n+1); however
at this point in the clock34xx.c code, N is one-based.
Hayati Bayrakdar <h-bayrakdar@ti.com> and Nishanth Menon <nm@ti.com> helped
track down this bug.
